Summary
Backed by the collective knowledge and experience of the world's leading Geographic Information Systems (GIS)
company, this book presents the concepts and methods that will allow users to unleash the full analytic power of
their GIS. Volume I of this two-part guide shows how to map and analyze patterns and relationships. It present
the most common methods for finding where things are located, what is at a particular point and what is nearby,
and how far apart they are. GIS users will learn how to find the most and the least of any quantity--such as chemicals
in the soil or traffic on a highway--and how to monitor things that change, such as erosion or toxic spills. The
pros and cons of each method of analysis are presented, as well as how to choose between different methods and
how to effectively communicate the results. Topics also include how to map categories and quantities, how to classify
data, and how to summarize data by geography.
